Using Long‐Term Ecological Datasets to Unravel the Impacts of Short‐Term Meteorological Disturbances on Phytoplankton Communities

open access: yesFreshwater Biology, Volume 70, Issue 5, May 2025.
ABSTRACT Extreme meteorological events such as storms are increasing in frequency and intensity, but our knowledge of their impacts on aquatic ecosystems and emergent system properties is limited. Understanding the ecological impacts of storms on the dynamics of primary producers remains a challenge that needs to be addressed to assess the ...

Pre‐aged organic matter dominates organic carbon burial in a major perialpine lake system

open access: yesLimnology and Oceanography, Volume 70, Issue 4, Page 911-924, April 2025.
Abstract Organic carbon (OC) burial in lake sediments is comparable to that in marine sediments globally. However, climatic and carbon cycle implications depend on the origin of buried OC. This study utilizes high‐resolution radiocarbon (14C) measurements in combination with stable carbon isotopes (13C) and total organic carbon/total nitrogen ratios to

A Model of Mountain Social‐Ecological Systems to Catalyze Multi‐Actor Collaborations Toward Sustainability

open access: yesEarth's Future, Volume 13, Issue 4, April 2025.
Abstract Addressing sustainability challenges in mountain regions where human activities strongly overlap requires multi‐actor collaboration and interdisciplinary methods. Yet, such collaborative processes need to account for the existence of diverse representations of mountain social‐ecological systems amongst actors.

Effects of Changing Snow and Ice Cover Conditions on Phytoplankton Chlorophyll‐a and Community Composition in a Mesotrophic Lake

open access: yesFreshwater Biology, Volume 70, Issue 3, March 2025.
ABSTRACT Ice and snow cover on lakes plays a fundamental role for under‐ice ecology by reducing water column mixing and light availability. Previous studies have shown that such reductions can significantly influence the growth and reproduction of phytoplankton, primarily focusing on changes in ice‐on and ice‐off dates in a warming climate.

Exploring the Interface Between Planetary Boundaries and Palaeoecology

open access: yesGlobal Change Biology, Volume 31, Issue 1, January 2025.
Planetary boundaries assist in delineating the ‘safe operating spaces’ beyond which critical Earth system processes could collapse. Knowledge of variability throughout the Holocene can be used in defining safe operating spaces and constraining limits of acceptable change. Palaeoecology can inform decisions about where change could be resisted, accepted

A new exceptionally preserved sawfly fossil (Hymenoptera: Pergidae) and an evaluation of its utility for divergence time estimation and biogeography

open access: yesSystematic Entomology, Volume 50, Issue 1, Page 237-251, January 2025.
We describe the first Australian Pergidae fossil species, Baladi warru, from McGraths Flat, a newly discovered Miocene Konservat‐Lagerstätte in Australia. The specimen contains pollen grains from Quintianapolis that were imaged with high‐resolution using SEM.

Thermal habitat fragmentation in stratified lakes induces resource waves that brook charr track across seasons

open access: yesOikos, Volume 2024, Issue 10, October 2024.
The spatial configuration of thermal habitats constrains the thermoregulatory performance of ectotherms. Thermal landscapes also vary through time, which is particularly relevant in seasonal environments such as temperate lakes. Indeed, elevated temperatures in the epilimnion of dimictic lakes during summer could substantially reduce the use of this ...
